[PATCH 05/17] ASoC: Intel: avs: Add code loading requests

[Pierre-Louis Bossart]

> +#define AVS_CL_TIMEOUT_MS	5000

it's not clear where this comes from, and it's also unclear why both
types of code loading would have the same timeout when the hardware is
so fundamentally different.

I've asked this before and I don't recall by this case requires an
initialization to zero?
